PurposeWith the rapid development of the service industry, service innovation has gradually become a hot topic in business today. How to further improve employees' service innovative behaviors has become critical to organizations' survival and success. Servant leadership, as a leadership style characterized by serving others, is closely related to employees' service innovative behaviors. Therefore, the purpose of this study is to develop a theoretical framework to examine the influence of servant leadership on employees' service innovative behavior, the mediating role of intrinsic motivation and the moderating role of identification with the leader.Design/methodology/approachTo test the theoretical model, a multi-time survey method was used to collect data from 381employees from a large high-tech company in Mainland China.FindingsThe results confirm that servant leadership can promote employees' service innovative behavior and intrinsic motivation. Meanwhile, employees' intrinsic motivation partly mediates the influence of servant leadership on their service innovative behavior. Moreover, this mediating relationship is conditional on the moderating role of individual identification with the leader in the path from servant leadership to individual intrinsic motivation.Research limitations/implicationsThe key limitation of this study lies in the representativeness of sample data, which is the convenience of non-probability sampling and self-reported data only from a large high-tech company in China.Practical implicationsThis study not only further verified a promotion factor of individual service innovative behavior from the perspective of leader influence, but also enriched the understanding of the positive influence of servant leadership on employees.Originality/valueThis study is the first to examine the relationships among servant leadership, employees' intrinsic motivation, identification with the leader and service innovative behavior. The results may help to open the “black box” of the relationship between servant leadership and employees' service innovative behavior by introducing their intrinsic motivation. The conclusions also indicate employees' identification with the leader is an important boundary condition among their relationships. Particularly, it not only moderates the relationship between servant leadership and intrinsic motivation, but also moderates the mediating role of intrinsic motivation.

Conventional theories of cognition focus on attention as the primary determinant of working memory contents. However, here we show that about one third of observers could not report the color of a ball that they had just been specifically attending for 5-59 s. This counterintuitive result was obtained when observers repeatedly counted the passes of one of two different colored balls among actors in a video and were then unexpectedly asked to report the color of the ball that they had just tracked. Control trials demonstrated that observers' color report performance increased dramatically once they had an expectation to do so. Critically, most of the incorrect color responses were the distractor ball color, which suggested memory storage without binding. Therefore, these results, together with other recent findings argued against two opposing theories: object-based encoding and feature-based encoding. Instead, we propose a new hypothesis by suggesting that the failure to report color is because participants might only activate the color representation in long-term memory without binding it to object representation in working memory.

A new angle: The insertion of a 2,2′‐biphosphole subunit into π‐conjugated systems offers a new way to control the HOMO–LUMO gap. Tuning of the dihedral angle (θ) between the two phosphorous heterocycles, either by metal coordination or covalent bonding through the P substitution can lead to control of the band gap. These new π‐conjugated systems can be used as emitting materials in white organic light‐emitting devices (WOLEDs).

Abstract:A synthetic route to novel benzofuran fused silole derivatives is described and the new compounds were fully characterized. These compounds showed optical and electrochemical properties that differ from their benzothiophene analog. Preliminary results show that these derivatives can be used as blue emitters in organic light emitting devices (OLEDs) illustrating the potential of these new compounds for opto-electronic applications.

In China, traditional culture advocates family consensus, and the advance care planning (ACP) engagement of family members is crucial to the implementation of ACP. However, there is still a lack of research on family members' engagement in ACP in mainland China. This study investigated the ACP engagement of family members of community-dwelling elderly patients with chronic diseases and provided evidence for further ACP intervention research. We conducted a mixed-methods sequential explanatory study, 273 family members were surveyed, and semistructured interviews were conducted. Following that, 12 family members were selected after statistical analysis to supplement the quantitative results. The results showed that the ACP engagement of family members of elderly patients with chronic diseases in the community was low, but the self-efficacy was higher. The age of family members, severity, and duration of patients' diseases were the main influencing factors for family members' ACP engagement. Traditional cultural, clinical decision-making mode, lack of understanding of ACP, and factors within the family may impede family members' engagement. This study showed that family-centered ACP practice has significant advantages in China and that future research should focus on the Chinese culture and medical system and highlight the role of families.

Monometallic gold(I)-alkynyl-helicene complexes (1 a,b) and bimetallic gold(I)-alkynyl-helicene architectures featuring the presence (2 a,b) or absence (3 a,b) of aurophilic intramolecular interactions were prepared by using different types of phosphole ligands (mono-phosphole L1 or bis-phospholes L2,3). The influence of the Au(I) d(10) metal center(s) on the electronic, photophysical, and chiroptical properties of these unprecedented phosphole-gold(I)-alkynyl-helicene complexes was examined. Experimental and theoretical results highlight the importance of ligand-to-ligand-type charge transfers and the strong effect of the presence or absence of Au(I) -Au(I) interactions in 2 a,b.
